For the first time in history, researchers have uncovered fossilized rod and cone cells. These are the parts of the eye that help animals see (including people). This discovery is not only remarkable in its novelty, but this also demonstrates that eye cells could have existed for at least the last 300 million years. Furthermore this study also suggests that ancient fish species actually saw in color as well, as described by the study’s scientists.

What we know about human vision is that our eyes rely on pigments that absorb light. Each of these pigments rest within the cells known as rods and cones. Cones are sensitive to color and they also help the brain to decipher small details as well as quick changes. Rods are also sensitive to stimuli,...
